Abstract [en]

Since the size of the homeownership ratio differs significantly between countries, it is important to understand the mechanisms that lie behind the decrease or growth of certain sectors of the housing market such as rentals and housing cooperatives. The aim of this study is to analyze the long-term dynamics of the new residential supply in Sweden's three largest cities for the period of 1990-2020 and estimate in what way market fundamentals affect it through new construction and housing conversions. We apply panel data methodology and, in distinction to previous research, consider the development of the housing market (urban growth) as physical volume. The results demonstrate that structural changes are driven mainly by fundamental demand factors and that the displacement effect occurs primarily in the market's rental sector and not in the owner-occupied segment. The apartment price per square meter, together with mortgage interest rates, are the major driving factors in the process of converting dwellings into housing cooperatives. Fundamental variables that affect new construction in both the rental and housing cooperative sectors are population and income growth. In the presence of a rent control environment, the rent or price level does not contribute to adding new units to the total housing stock.

Bostadsmarknadens dynamik
Abstract [en]

The dynamics of housing markets constitute a complex phenomenon. The body of research is vast and includes thousands of studies done on the national and international level. Empirical evidence indicates that housing markets differ in local institutional arrangements and that these might affect the ways they develop over time. To analyze housing market dynamics in various institutional environments and to increase our understanding of them is the main objective of this thesis.

The scope of research includes analysis of relevant theories and empirical models that might explain development of house prices over the long run. Given that prices affect housing construction, this thesis also aims to deepen understanding of the impact of the relationship between new construction and underlying fundamentals, together with various institutional arrangements that might differ between countries. In particular, they include bank lending policies, valuation methods for mortgage purposes, different regulatory measures like rent control, as well as land and building policies.

The Swedish apartment market was chosen for empirical analysis. The analysis is carried out by a combination of qualitative and quantitative methodology and applies several research methods, such as systematic literature review, and panel data analysis with application of advanced econometric techniques like Dynamic Ordinary Least Squares, Fixed and Random Effects and Seemingly Unrelated Regressions. Four studies are carried out using these methodologies.

The results indicate that the interest rate, disposable income and population growth seem to be major determinants of house prices according to studies found in the empirical literature (Paper 1). The study also classifies house price determinants in relation to the size of their elasticities. However, fundamental factors cannot always provide an explanation for the deviations in house price dynamics in different countries, whereas the institutional environment might do so (Paper 2). The analysis demonstrates that land prices and building policies, along with a number of market fundamentals, affect the average size of an apartment in new residential construction (Paper 3). In the presence of rent control, the rent or price level does not contribute by adding new units to the total housing stock. In addition, the displacement effect occurs primarily in the market’s rental sector and not in the tenant-owned apartments segment (Paper 4).

This research contributes to a better understanding of housing markets dynamics and suggests policy implications that might reduce the risks for housing bubbles and improve the socio-economic development of the society over the long run.

Abstract [sv]

Bostadsmarknadens dynamik är ett komplext fenomen. Forskningen är enorm och omfattar tusentals studier gjorda på nationell och internationell nivå. Empiriska studier tyder på att bostadsmarknaderna skiljer sig åt i lokala institutionella arrangemang och det kan påverka hur de utvecklas över tiden. Att analysera bostadsmarknadens dynamik i olika institutionella miljöer och att öka vår förståelse om den är huvudsyftet med denna avhandling.

Forskningsfokus ligger på analys av relevanta teorier och empiriska modeller som kan förklara utvecklingen av huspriser på lång sikt. Med tanke på att priserna påverkar bostadsbyggandet är fokus också på att förstå effekterna av sambandet mellan nybyggnation och underliggande fundamentala faktorer tillsammans med olika institutionella arrangemang som kan skilja sig åt mellan länder. De inkluderar banklånepolitik, värderingsmetoder, olika regleringar som hyresreglering, restriktioner av mark- och nybyggnation.

Den svenska bostadsmarknaden valdes för tillämpad analys. Analysen utförs med kombinationen av kvalitativ och kvantitativ metodik och tillämpar flera forskningsmetoder som systematisk litteraturgenomgång och paneldataanalys med tillämpning av avancerade ekonometriska tekniker som Dynamisk Minsta Kvadratmetod (Dynamic Ordinary Least Squares), Fixa- och Slumpmässiga Effekter (Fixed and Random Effects) and Skenbart Orelaterade Regressioner (Seemingly Unrelated Regressions). Fyra studier genomförs med dessa metoder.

Resultaten från empirisk litteratur tyder på att ränta, disponibel inkomst och befolkningstillväxt verkar vara avgörande faktorer för bostadsprisutveckling (Artikel 1). Studien klassificerar fundamentala faktorer i förhållande till storleken på deras elasticitet. De grundläggande faktorerna kan dock inte alltid ge en förklaring till avvikelserna i bostadsprisdynamiken i olika länder, men institutionell miljö kan göra det (Artikel 2). Analysen visar att restriktioner av markpriser och nybyggnation, tillsammans med ett antal grundläggande faktorer, påverkar den genomsnittliga storleken på lägenhet i nybyggnation (Artikel 3). Hyres och prisnivån på bostadsmarknaden med hyresregleringen bidrar inte till utvecklingen av det totala bostadsbeståndet. Undanträngningseffekten uppstår främst i marknadens hyressektor men inte i bostadsrättssegmentet (Artikel 4).

Denna forskning bidrar till en bättre förståelse av bostadsmarknadernas dynamik och föreslår politiska åtgärder som kan minska riskerna för bostadsbubblor och förbättra den socioekonomiska utvecklingen på lång sikt.
